Making The Container Of A Validation Summary Visible When The Validation Summary Becomes Visible?

Nov 29, 2010

I have the following markup. The errorPanel was first only used to show server side exception messages, and works fine like that. Now I'd like to incorporate my validation summary into that same errorPanel.

[code]....

My problem now is that the required validation happens client side, and I want to keep that, so I have no server side opportunity to make errorPanel visible, in order to make the validation summary visible.

I see I have two options: Do validation server side, and use my code there to make the panel visible, or hook into the client side code somehow and catch an event there when the summary should be made visible, and then also make the errorPanel visible. How could I go about the latter?

Web Forms :: Open Save Dialoge From Button Click To Save Including CSS?

Feb 4, 2011

My page (which basically contains a pair of Repeaters) renders and is displayed to the user.I'd like to have a "Download" button on the page which, when clicked, will propmt the user to save the page locally as an html file without losing any of the CSS formatting.

My CSS files are linked to via a Master Page.Currently, I have the button linked to some javascript that open will the Save As dialog, but all of the CSS formatting is lost, and it saves the page .I'm assuming that the button will need to open a new page which will re-create the data for the Repeaters and then save using StreamWriter, but I'm not exactly sure if that's right or how best to do it.

Web Forms :: To Validate Multiplevalidation Groups With The Click Of One Button?

Apr 1, 2010

I need to be able to validate multiple validation groups with the click of one button. My Form consists of two text boxes and a drop down list for input. The form also, currently, has three buttons, one for each control. Each of those buttons are tied to a validation control and if the validation is successful, it will add the user inputted data into a database that I have. The interesting part comes when I need to add a forth button which will act as a "Save All" Button. When this button is clicked, I need it to fire the three validation groups.

Is it possible to add multiple validation groups to the "Save All" Button?

Forms Data Controls :: How To Save Listview Contents On A Button Click

Jan 6, 2010

i have a listview which contains a text box and a drop down control (which makes it kind of a layout ...a text box along side a drop down control in each row). there can be any number of rows in the listview depending upon a user entry (an integer).

after i have filled all the text boxes and changed the drop down controls to their associated values (for each text box), i want to save everything that i have filled. i have a SAVE button OUTSIDE the listview, and i want to (probably) iterate through all the rows of the listview and save all the contents in the textboxes to a collection object, where each collection item will be a row with textbox's text and dropdown's selected index value.
